A NOTE ON STELLARIA PUBERA MICHX. 
C. A. WEATHERBY. 
AN attempt to name accurately a Stellaria found growing as an 
introduced plant at Wilton, Conn., by Miss Anna E. Carpenter and 
persistent there for at least six years, has involved me in a survey 
of the forms referred to S. pubera, which, though necessarily some- 
what cursory, has yielded results perhaps worth recording. Through 
the kindness of Dr. W. R. Maxon, I have had the privilege of examin- 
ing the material of S. pubera in the United States National Herbarium; 
and Mr. C. C. Deam has generously lent me the fine representation of 
the species in his private herbarium. 
Although varying much in leaf-form, the great majority of speci- 
meus from east of the Alleghanies are constant in the following 
characters. The median leaves of the flowering stems are sessile or 
subsessile and not over 4 cm. long. The larger, oblong-lanceolate 
to broadly oval leaves of the sterile shoots are likewise sessile or 
subsessile. Thesepals are 4-5 mm. long (rarely a littlelonger), broadly 
ovate to oblong-ovate or rarely oblong-lanceolate, obtuse to acutish, 
and, though often pilose on the back, are not ciliate or only slightly 
and inconspicuously so at the very base. They are usually shorter 
than the petals. This common form is, as indicated by Michaux's 
description and his type locality, no doubt typical S. pubera. 
At scattered stations nearly throughout the range of the species 
occur larger plants in which the oblong-lanceolate to broadly oval 
median leaves of the few-flowered fertile stems are 6-11 cm. long 
and the sepals generally 5-6 mm. long. This is Alsine pubera ten-
